Bilbao's elegant city hall in the Plaza Erkoreka Ernesto dates from 1892 and was designed by Joaquin Rucoba, with a spire and a magnificent façade featuring balconies, columns and a sweeping staircase. The highlight of the interior is the 'Arab Room', an opulently decorated chamber used for civil marriage ceremonies. Guided tours, lasting about an hour are available, though these need to be booked in advance by phone.
